The index consists of Euro-denominated inflation-linked government bonds that are used for diversification purposes and for explicit protection against inflation.

Constituents require a minimum outstanding of €1 billion, one year to maturity at the rebalancing date, and are investment grade.

Returns for this index, denoted as HDG, reflect those in each country's local market, as well as the costs and returns of forward currency contracts intended to offset gains or losses that would otherwise be incurred as the result of converting back to US Dollars (USD).
